Virginia Commonwealth University in Richmond is the latest institution to jump aboard the biometrics bandwagon. On Wednesday, the school announced it had added two iris cameras to the campus dining hall so that students can use their eyes instead of their ID for access.

“Students won’t need their ID to enter the dining center anymore,” Stephen Barr, VCU director of campus services, said in a statement Thursday. “With iris identification, it’s as simple as a camera taking a picture of their eyes and two seconds later they walk through.”
